Sink leaks and drain problems we repair in Des Plaines
Water in the sink cabinet means something is loose, cracked or worn out: a trap nut, a strainer gasket, a dishwasher hose or the drain pipe in the wall. We find which one in your Des Plaines kitchen and repair it so the cabinet floor stays dry.
Leak around the drain in the sink bowl
If the leak appears only after the bowl is filled, the seal between the strainer and the sink is gone. We pull the strainer, clean it and reseal it.
Old S-trap or wrong parts
Sinks hooked up with corrugated tubing or an S-trap tend to leak and smell. A properly sized P-trap fixes both.
Cracked or corroded drain pipe
Old chrome traps rust through from inside and plastic pipe can crack where it was overtightened. The damaged section is cut out and replaced.
Swollen or stained cabinet floor
A long, slow leak turns the cabinet floor soft and dark. After the repair we can cut out the damaged panel and fit a new floor in the sink base.
Drain sealed with tape or putty
If someone wrapped the pipe to stop a drip, the joint under the wrap is failing. We cut it out and rebuild it.
Drip from the trap or slip joint
Slip-joint washers flatten and dry out over the years. When a trap keeps weeping no matter how hard you tighten it, the trap assembly is replaced.
Musty smell under the sink
If the sink base smells damp, water is getting somewhere. Finding a small leak early saves the cabinet and the floor below.
What the repair visit covers
- Dry and inspectEverything under the sink is cleared and wiped dry so we can see where water appears.
- Locate the leakWe test each part separately until the drip shows up.
- Basket strainer resealA new basket strainer if the old one is corroded or cracked.
- Trap and tailpieceThe trap assembly rebuilt with matching parts and a proper seal.
- Dishwasher and disposal connectionsHose clamps, inlet and outlet fittings checked and replaced.
- Drain pipe and wall connectionThe trap adapter or drain arm at the wall rebuilt when it leaks.
- Supply side checkWe look at the stops and faucet lines too, since they leak into the same cabinet.
Parts we replace
Plumber's putty and gasketsPutty or rubber gaskets seal the strainer to the sink; stone sinks often need a putty that won't stain.
PVC traps and tailpiecesPlastic trap parts that don't rust and are easy to service later.
Basket strainersStainless or brass strainers matched to the sink, set in putty or with a gasket.
Dishwasher hose and air gapA new drain hose, clamps and a high loop or counter air gap where required.
Transition couplingsShielded couplings and adapters to join new PVC to old galvanized or cast iron.

Kitchen Sink Leak & Drain Repair questions from Des Plaines homeowners
Why does my sink leak after installing a dishwasher?
The new hose connection is the likely culprit. We fix it and make sure there is a high loop or air gap.
Is it safe to keep using the sink?
With a small drip, put a bowl under it and use the sink lightly until it's repaired. A steady leak means stop using that drain.
Can you fix water damage to the sink cabinet?
Yes. Once the leak is fixed and dry, we replace the cabinet floor or add a liner to protect it.
Can a leaking sink cause mold?
It can, if the leak goes on for weeks. We check the cabinet and wall for moisture during the repair.
Why is my kitchen sink leaking underneath?
Under-sink leaks usually come from slip joints, the strainer, the dishwasher connection or the pipe itself. We test each until we find it.
Does Des Plaines require a licensed plumber for sink leak repair?
Plumbers need a State of Illinois license; no City fees. Our plumbing connections are made by licensed plumbers.
